Question

Ca(²+)+CO3(²-)=CaCO3​

Answer 1

Ответ:

Объяснение:

CaCl2 + Na2CO3 = CaCO3↓ + 2NaCl

Ca(2+) + 2Cl(-) + 2Na(+) + CO3(2-) = CaCO3↓ + 2Na(+) + 2Cl(-)

Ca(2+) + CO3(2-) = CaCO3↓

Answer 2

The chemical equation you've provided seems to represent the reaction between calcium ions (Ca²⁺) and carbonate ions (CO₃²⁻) to form calcium carbonate (CaCO₃). However, there are a couple of issues with the equation:

1. Charges: The charges on calcium ions and carbonate ions are not correctly represented. Calcium ions have a charge of +2 (Ca²⁺), and carbonate ions have a charge of -2 (CO₃²⁻). In your equation, you've written "Ca(²+)" and "CO3(²-)", which seem to be incorrect representations of the charges.

2. Balance: The equation is not balanced. Chemical equations need to be balanced to accurately represent the conservation of mass and charge. Each side of the equation should have an equal number of atoms of each element.

The balanced chemical equation for the reaction between calcium ions and carbonate ions to form calcium carbonate is:

Ca²⁺ + CO₃²⁻ → CaCO₃

Please note that this equation is balanced in terms of charge and atoms of each element. However, if you're looking for a full chemical equation that takes into account the physical states of the reactants and products, it would look something like:

Ca²⁺(aq) + CO₃²⁻(aq) → CaCO₃(s)

In this equation, "(aq)" represents an aqueous solution (dissolved in water), and "(s)" represents a solid precipitate.
